IPC: B41J2/055
Filed: 1985-11-26
Abstract: PURPOSE:To prevent bubble suction phenomenon through a nozzle aperture due to the dropping of an ink jet head during its storage or impact while in transit by providing a movable ink check valve so as to block an ink reservoir. CONSTITUTION:During initial ink filling, an ink check valve 13 is away from a mural ink check valve seat 201, 202 and a partition 19, and a check valve cavity 50 is filled unit an ink circulation hole 401, 402.
